PIPE CLAMP AND HANGER.

ll'o. erases,

Tooll whom it may concern:

Be it known that I, ROBERT Amazon, a citizen of the United 'States, and resident of St. Louis, Missouri, have invented cer-. tain new and useful Improvements in Pipe Clamps and Hangers, of which the following is a specification containing a full, clear,

the accompanying drawings, forming'a part hereof,

My invention relates to a pipe clamp and hanger, and hasfor its object the construction and arrangement of a simple and in-- expensive device particularly adapted "for use in clamping the train. pipes and fittings of air brake and steam heating systems, which clamp is so constructed as to be easily and quickly assembled or taken apart, and the members of which clamp are drawn 1 tightly against the pipe and held in a clamping: position without the use of bolts and nuts, which latter tend to loosen and become detached as a result of vibration.

Where bolts and nuts are utilized as a means of drawing the parts of a clamp to gether, and causing them to grip a pipe, much time and labor is involved in assem-' bling or detaching the members of the clamp; whereas, in my improved device, a spring key or cotter is made use of, which very effectually locks the parts of the clamp together," and at the same time draws the to,very tightly grip the pipe and maintain the same a inst both rotary and longitudinal movement. i

My improved clamp andhanger consists of a pair of interlocking members, one of which is fixed in any suitable manner to the car body, and which members move to. and from one another by the arrangement of oppositely disposed lugs having similarly inclined faces, and said members being locked together and clamped upon the pipe by a single pin or spring cotter, which is easily and quickly'inserted. or removed.

My invention further consists in certain, novel features of construction and arrange ment of parts, which will be hereinafter more fully set forth, pointed out in the Figure l is a side elevation of the clamp and hanger, and showing a pipe engaged thereby; 31g. 21s a front elevatior of the clamp and hanger; Fig. is a vertical see Specification of Letters Patent.

-Beferring by reference characters to the acco1npanymg--drawings: 1 designates a vertically disposed plate, the'upper end of which i perforated, as designated by 2, in order that said plate maybe bolted to a-portion. of the car frame, and formed integral with the lower end of the plate is a semi-circular plate 3, the upper end of which is incllned, preferably at an angle of approxie nately 45, and the side of the plate 1 where it wins with said plate 3 is cutaway or notched, as designated by 4, thus forming in.- clined shoulders 5 on the upper side of the plate 3. A strengthening rib 6 is formed integral with the rear face and lower end of the plate 1, and extends ddwnwardly onto the inclined upper end of the plate 3; and formed integral with the lower end of th plate 3- is a downwardly pending incline-d tongue, or plate 7, there being notches 8 formed between the upper end of said plate and the lower end of the curved plate 8, thus forming inclined shoulders 9 .it the upper end of said plate 7, which we disposed at the same angle as are thi shoulders Formed integral with the top surfaces of the platesB and 7 is a lug 10, whi .h is equal in width to the width of that portion of the plate 3 between the notches 8, arid the upper surface of said big 10 is formel by a continuation of the curved iDIlBP'ST rface of the plate The lower corners of the plate 7. at the sides thereof, are roundr d oif, or bev eled inwardly, as designated by 11, in order to guide the ends of aspring COTl'il. or key, (hereinafter described.)

The clamping member of tie (Em ii-c comthe upper ends thereof, are lugs 16, the

lower faces of which are inclined and engage the shoulders 9 at the upper end of the plate 7 when the device is assembled.

.Formed through the plates 15 are the oppositely disposed pairs of apertures 17, and formed integral with said plates and uniting the lower ends thereof is the transversely arranged plate 18, the top side of which is provided with transversely arranged ribs 19, between the apertures 17.

When my improved clamp and hanger is in use, the plate 1 is rigidly fixed to the car body, and the pipe A 1s positioned'against the inner faces of the curved plate 3. The clamping member, comprising the plate 12 and parts integral therewith, is now positioned against the outside of the pipe with *the plates 15 inclosing the tongue 7, which tongue passes between the lugs 16 and the rear end of the plate 18 when the two members of the device are assembled, thus bringing the shoulders 9 against the under side of the lugs 16.- During this action, the up 35 per end of the plate 12 is so manipulated as that the lugs 14 engage over the shoulders 5 at the upper end. of the plate 3, and the clamping plate 12 is now moved toward the plate 3 at an angle corresponding to the engaging faces' o the lugs 14 and 16 and shoulders 5 and 9 until the plate 12 clamps the pipe against the plate 3, after which a key or spring cotter B is inserted through one pair of apertures 17 and on being driven between the top surface of the plate 18 and the under side of the tongue 7 tends to force said tongu'e and plate apart, which action causes the plate 12 to move toward tightly grip the pipe and maintain it against both rotary and longitudinal movement.

The lower ed es of the plate 7 are rounded or beveled, as esignated by 11, in order to guide the ends of'the split key or cotter beneath said plate 7 and, if desired, the apertimes 17 may be reamed or tapered in order that the key or cotter will be readily guided therethrough when forced into position.

By providing a plurality of pairs of apertures 17, the clamp is made adjustable so that it may be tightened on pipes of various sizes.

The plate 12 moves to and from the pipe and the opposite plate 3 when tightened or loosened by reason of the inclination of the interlocking lugs 14 and 16 and shoulders 5 and 9, and said plates are very rigidly locked together and tightly clamped upon the pipe by means of the spring key or cotter, thus dispensing'with the use of bolts and nuts, which latter very quickly work loose as a result of vibration, and are much more expensive than a key or cotter.

In;soiue instances, the upper end of the plate l may be -provided with a screw threaded shank, (as shown in Fig. 6,) which arrangement permits said plateto be screwed into a tuition of the car frame. a In a modified form of the device, (as shown in Figs. 7 to 9,.inclusive,) the lates 3 and 12 are constructed to be clampe onto a hexagonal part or fitting of the air brake or heating system, such as is often found on a cock or valve, and the spring key or cotter may be made to pass diagonally between the tongue 7 and late 18, instead of being transversely positioned as, in the construction previously described. Where this form of the device is employed, a pair of grooves 20, of diiferent depths are'formed in the top face of the plate 18, which grooves cross one another, which arrangement provides for a clamping action the entire width of the plate by the spring key or cotter, when the same is ositioned in one of said grooves.

While this manner of positioning the key or cases; the only difference being the direction in which the key or cotter is inserted.

My improved device performs the function of both a clamp and hanger, comprises but three pieces, including the locking key or cotter, is easily and quickly assembled or taken apart, and very rigidly clamps and supports a pipe.

I claim 1. A pipe clamp and hanger, com rising a pair of interlocking semi-circular p ates, 1nclined shoulders formed on the sides of one of the plates, hook shaped lugs formed on the opposite plate which inclose and bear upon the inclined shoulders of the opposite plate, a pair of interlocking plates integral with the semi-circular plates, and means arranged between the interlocking plates whereby the semi-circular plates are caused to move to-' ward one another to engage and clamp a pipe.
